#466 - Look-Air / Square Jam Hybrid
Divide the grid into square regions of orthogonally connected cells and s hade some cells so that each region is either fully shaded or fully unshaded. Region borders may not form any four-way intersections. Clues represent how many of the five cells forming a cross around the clue (including itself) are shaded. Two shaded squares may not be orthogonally adjacent. Two shaded squares of the same size may not have a vertical or horizontal line of unshaded cells between them, unobstructed. Solve online
